         (a) Any termination of the Executive's employment by the Company or the
Executive pursuant to subsections 8(b), (c), (d) or (e) shall be communicated by
a written notice (a "Termination Notice") to the Executive or the Company, as
applicable, in accordance with Section 12 hereof. For purposes of this

shall indicate the termination provision relied upon in this Agreement, as well
as the effective date of such termination (the "Termination Date") and, except

facts and circumstances claimed to provide a basis for termination of the
Executive's employment under the provision so indicated. Provided that the

Agreement provides the exclusive remedies and exclusive severance pay for any
termination of the Executive, and if the employment of the Executive is
terminated, the Company shall have no further obligations except as expressly
provided under this Agreement, or as otherwise provided by law. As a condition
to receiving any payments upon or after termination for any cause (other than
amounts, if any, due for past services, or other than the payment of amounts
accrued and unpaid under Section 4 hereof through the Termination Date), the
Executive must release the Company from all potential claims for the payment of
monies which may be due under this Agreement.

         (b)     Cause.

                  (i) The Company may, at any time, and in its sole discretion,
         terminate the employment of the Executive hereunder for Cause. For
         purposes of this Agreement, "Cause" means the Executive's (1)
         substantial and material violation of the policies or procedures of the
         Company or any of its Affiliates; (2) willful and reckless failure to
         perform the duties or responsibilities set forth under Section 3 of
         this Agreement; (3) gross insubordination or recklessly and
         intentionally taking of any action in conflict with the interests and
         objectives of the Company or any of its Affiliates; (4) commission of a
         fraudulent or dishonest act in connection with his employment with the
         Company or any of its Affiliates; or (5) plea of guilty or nolo
         contendere to or conviction of any felony or an act of moral turpitude.

                  (ii) If the employment of the Executive hereunder is
         terminated pursuant to this subsection 8(b), the Company shall have no
         further obligations to the Executive hereunder after the Termination
         Date other than the payment of Base Salary accrued and unpaid under
         Section 4 hereof through the Termination Date, or except as otherwise
         provided by law.

         (c) Termination Without Cause. At any time after the initial year of
the term of this Agreement, in the event the Company desires to terminate the
employment of the Executive hereunder for actions other than Cause, or for any
or no reason, ("without cause"), by delivery to him of a Termination Notice,
such termination shall be

<PAGE>

effective thirty (30) days after the date of the Termination Notice; provided
however, the Company shall be required to pay the Severance Pay to Executive,
as defined in and according to the terms of Section 8(h) below.

         (d) Resignation. The Executive shall be entitled to terminate this
Agreement at any time, for any reason, by providing the Company with a
written Notice of Resignation at least thirty (30) days prior to his intended
resignation date.

         (e) Disability

             (i) In the event that the CEO, acting reasonably and in good
         faith, determines that the Executive is incapacitated by reason of a
         physical or mental illness which is long-term in nature and which
         prevents the Executive from performing the essential functions of his
         position, with reasonable accommodation, and the CEO has been advised
         in writing by the Company's physician, following a physical
         examination, that such incapacity can reasonably be expected to prevent
         the Executive from performing the essential functions of his position
         for a period of at least six (6) months in any twelve (12) month
         period, the CEO may terminate the Executive's employment hereunder;
         provided however, the Company shall be required to pay the Severance
         Pay to Executive, as defined in and according to the terms of Section
         8(h) below. The Company may require the Executive to have the physical
         examination described in the preceding sentence at any time but only
         for the sole and limited purpose of determining whether or not the
         Executive has a long-term disability, and the Executive agrees to
         submit to such examination no later than ten (10) days after receiving
         written notification from the Company.

             (ii) If the employment of the Executive hereunder is terminated
         pursuant to this subsection 8(e)(i) because of a long-term
         disability, the Executive shall receive the Severance Pay in
         accordance with Section 8(h), as well as payments pursuant to the
         Company's disability policy which is in effect for executives of the
         Company, Base Salary and Variable Compensation earned through the
         Termination Date. If the employment of the Executive hereunder is
         terminated pursuant to this paragraph 8(e)(i), the Company shall
         have no further obligations hereunder except as expressly provided
         under this paragraph 8(e)(i), or as otherwise provided by law.

             (iii) Upon the termination of this Agreement by reason of the
         Executive's disability, such termination shall not terminate or
         adversely affect any rights of the Executive then vested or accrued
         under any disability or other fringe benefit program of the Company
         then in effect. During the period of the Executive's disability
         prior to the termination of this Agreement, the Executive shall be
         entitled to receive any disability benefits provided by the Company
         as part of its short term or long term disability plan, if any.

             (iv) The Executive represents to the Company that, as of the
         date of this Agreement, to the best of his knowledge, he is in good
         health and is not aware of any health condition that is likely to
         lead to a temporary or long-term disability within the Employment
         Term.

         (f) Death. If the Executive dies during the Employment Term, the
employment of the Executive hereunder shall terminate immediately upon his
death. If the employment of the Executive hereunder is terminated pursuant to
this subsection 8(f), the Company shall have no further obligations hereunder
after the date of death other than the payment to the Executive's estate,
legal representatives, heirs, successors, assigns or other beneficiaries of
Base Salary and Variable Compensation accrued and unpaid under Section 4
through the Termination Date. If the employment of the Executive is
terminated pursuant to this subsection 8(f), the Company shall have no
further obligations hereunder except as expressly provided under this
subsection 8(f), or as otherwise provided by law.

         (g) Voluntary Termination. If the Executive voluntarily terminates his
employment hereunder, the Company shall have no further obligations to the
Executive hereunder after the Termination Date other than the payment of Base
Salary and any Variable Compensation accrued and unpaid under Section 4 hereof
through the Termination Date, except as required by law.

         (h) Severance Pay. If, pursuant to this Agreement, Executive is to be
paid Severance Pay, then the Company shall pay to the Executive, in a lump sum
cash payment within five (5) days after Executive's execution of a valid release
as set forth in Section 8(a) above, the following (the "Severance Amount"):

             (i)   Executive's earned but unpaid Base Salary through the
                   Termination Date;

             (ii)  A prorated amount of Base Salary as in effect immediately
                   prior to the date of termination, but without regard to
                   any compensation deferral election under any plan, program
                   or arrangement, qualified or nonqualified, maintained or
                   contributed to by the Company, including but not limited
                   to a cash-or-deferred arrangement described in Section

                          Executive's employment, the Prorated Amount shall
                          be the equivalent of twelve months' Base Salary.

                   (b)    In the event the Company terminates the Executive's
                          employment pursuant to the terms of Sections 8(c)
                          or 8(e) after the first twelve months of
                          Executive's Employment, the Prorated Amount shall
                          be the equivalent of one month's Base Salary for
                          every month remaining between the Termination Date
                          and August 31st, 2001, but in no event shall be

                   calendar months of continued medical coverage according to
                   the same terms to which he was entitled to medical
                   coverage on the date immediately preceding the termination.

         9.  DISCLOSURE OF INFORMATION.

         (a) The Executive shall not, during or after the Employment Term,
disclose any confidential or proprietary information of the Company or any of
its affiliates to any person, firm, company, association, limited liability
company, or other entity for any reason or purpose whatsoever, except in the
performance of the duties assigned to the Executive in this Agreement, nor
shall the Executive make use of any such confidential or proprietary
information for his own purpose or for the benefit of any person, firm,
limited liability company, company or other entity, except the Company or any

         (c) The Executive acknowledges that disclosure of, or any
contravention of this Section 9, regardless of the materiality of such
disclosure or contravention, may result in immediate, direct, irreparable and
substantial damage to the Company for which a remedy at law may not be
sufficient and therefore, the Company shall be entitled to apply for
injunctive relief and/or specific performance by any court of competent
jurisdiction, in addition to any other rights or remedies it might have at
law or equity.

         10.     NON-COMPETITION.

         (a)     Executive acknowledges that, in exchange for the execution

adequate consideration for the execution of the non-competition restriction
set forth in this Section 10.

         (b)     During the Employment Term and thereafter, until the end of
a period of twelve months commencing on the Termination Date (the

         connected or affiliated or associated with or assist any corporation,
         partnership, limited liability company or partnership, proprietorship,
         firm, association or other entity which is engaged in any manner in, or
         otherwise competes with, the Company (including, without limitation,
         any strategic plans) in the business field, products or services of the
         kind and character in which Executive was engaged, either directly or
         indirectly, on behalf of the Company. The restriction herein contained
         shall be limited in geographical scope to each of the geographical
         areas in the United States in which the Company conducts business,
         provides services or sells products at any time during Executive's
         employment, which the Parties hereto acknowledge is national in scope;
         and

                 (ii) Executive shall not, directly or indirectly, solicit,
         employ or otherwise engage or assist, as an employee, independent
         consultant or otherwise, in the solicitation, employment or engagement
         of any person who is an employee of the Company or any affiliate of the
         Company, or in any manner induce or attempt to induce any employee of
         the Company to terminate his or her employment with the

         Company. For purposes of this covenant, "an employee of the Company"
         shall refer to employees who are still actively employed by, or

         solicitation, employment or engagement. Additionally, the Executive
         shall not tortiously interfere with the relationship of the Company
         with any person who is a customer, vendor, supplier or consultant of
         or to the Company. For purposes of this covenant, "a customer,

         customers, vendors, suppliers or consultants who are still actively
         doing business with or serving the Company at the time of the
         attempted interference.

         (c) The Executive and the Company agree that, if, in the opinion of any
court of competent jurisdiction, the covenants of non-competition and
non-solicitation are not reasonable in any respect, such court shall have the
right, power and authority to excise or modify such provision or provisions of
these covenants as to the court shall appear not reasonable and to enforce the
remainder of these covenants as so amended.

         (d) The Executive acknowledges that disclosure of, or any
contravention of this Section 10, regardless of the materiality of such
disclosure or contravention, may result in immediate, direct, irreparable and
substantial damage to the Company for which a remedy at law may not be
sufficient and, therefore, the Company shall be entitled to apply for
injunctive relief and/or specific performance by any court of competent
jurisdiction, in addition to any other rights or remedies it might have at law
or equity.

         12. CHANGE IN CONTROL. If the Company should undergo a "Change in
Control" as defined in this section, the parties agree as follows:

         (a) Compensation. In the event that this Agreement is terminated at
any time within two (2) years after the date of a Change in Control, as
defined in this section, by the Company communicating a Notice of Termination
Without Cause, the Company agrees to pay the Executive the Severance Pay
required to pursuant to Section 8(h). These payments shall be made within
thirty (30) days after the effective date of termination. Further, in the
event Executive desires to terminate his employment for "Good Reason" as
herein defined, by reason of a Change of Control, Executive shall be paid the
Severance Pay required pursuant to Section 8(h). The term "Good Reason" shall
mean (i) the demotion (i.e. reassignment to a position of materially lesser
rank or status), (ii) substantial reduction in annual Base Salary, (iii)
reduction in benefits (unless such reduction is made uniformly in a plan of
general application to all of the Company's substantially similar employees),
or (iv) reassignment to a location that is more than fifty (50) miles from
the Executive's then current residence without his consent.

         (b) Benefits. In addition, Executive will be entitled to twelve (12)
calendar months of continued medical coverage according to the same terms to
which he was entitled to medical coverage on the date immediately preceding
the Change in Control, as well as the other benefits required pursuant to
Section 8(h).

         (c) Definitions. For purposes of this Agreement, a "Change in
Control" shall mean a change in ownership or control of the Company effected
through any of the following transactions:

             (i) a merger, consolidation or reorganization approved by the
         Company's stockholders, unless securities representing more than fifty
         percent (50%) of the total combined voting power of the voting
         securities of the successor corporation are immediately thereafter
         beneficially owned, directly or indirectly and in substantially the
         same proportion, by the persons who beneficially owned the Company's
         outstanding voting securities immediately prior to such transaction,

             (ii) any stockholder-approved transfer or other disposition of
         all or substantially all of the Company's assets, or

             (iii) the acquisition, directly or indirectly by any person or
         related group of persons (other than the Company or a person that
         directly or indirectly controls, is controlled by, or is under common
         control with, the Company), of beneficial ownership (within the meaning
         of Rule 13d-3 of the Securities Exchange Act of 1934) of securities
         possessing more than fifty percent (50%) of the total combined voting
         power of the Company's outstanding securities pursuant to a tender or
         exchange offer made directly to the Company's stockholders which the
         Board of Directors recommends such stockholders to accept.

         13. ENTIRE AGREEMENT. This Agreement contains the entire
understanding between the Company and the Executive with respect to the
employment of the Executive and supersedes all prior negotiations and
understandings between the Company and the Executive with respect to the
employment of the Executive by the Company. This Agreement may not be amended
or modified except by a written instrument signed by the Company and the
Executive.

         14. SEVERABILITY. In the event any one or more provisions of this
Agreement is held to be invalid or unenforceable, such invalidity or
unenforceability shall attach only to such provision or part of such
provision,

EXECUTIVE EMPLOYMENT AGREEMENT - PAGE 8
<PAGE>


and shall not affect the validity or enforceability of the other provisions
hereof and the remaining part of such provision and all other provisions
shall remain in full force and effect.

         15.      APPLICABLE LAW: SUBMISSION TO ARBITRATION.

         (a) Applicable Law. This Agreement and the rights, obligations and
relations of the parties hereto shall be governed by and construed and enforced
in accordance with the laws of the State of Texas without regard to the rules
thereof relating to conflict of laws. However, both Parties acknowledge that
Section 16(b) is governed by the Federal Arbitration Act and to the extent that
it is inconsistent with Texas law, it will supercede Texas law relating to the
arbitrability of any disputes.

         (b)   Arbitration.

                  (i) Any disputes between the Parties including statutory
         and/or common law tort claims, other than disputes relating to the
         operation of and the enforcement of Sections 9 and 10 hereof, which
         cannot be resolved by negotiation between the parties hereto, shall be
         submitted to, and determined by, arbitration in Dallas, Texas in
         accordance with the rules of the American Arbitration Association
         ("AAA") and the provisions of this Section 16, and the parties hereto
         agree to be bound by the final award of the arbitrator in any such
         proceeding. Notwithstanding the foregoing, the Executive and the
         Company acknowledge that claims for workers' compensation or
         unemployment compensation benefits are not covered by this Agreement.
         Moreover, the Executive and the Company further acknowledge that this
         Section shall not prohibit the Executive from filing a charge or
         complaint with any governmental agency.

                  (ii) Either party may initiate an arbitration proceeding by
         delivery of written notice to the other party hereto. Resolution of
         such dispute shall be resolved by a majority vote of a panel of three
         arbitrators. Within 30 days after giving or receiving a demand for
         arbitration, the Company and the Executive shall each select one
         arbitrator. Such arbitrators shall be freely selected and the parties
         shall not be limited in their selection to any prescribed list. The
         arbitrators chosen by the Company and the Executive shall, by mutual
         consent, select the third arbitrator.

                  (iii) The decision of the arbitrators shall be in writing and
         presented in separate findings of fact and law. The award of the
         arbitrators shall be final and binding on the parties from which no
         appeal maybe taken and an order confirming the award or judgment upon
         the award may be entered into in any court having jurisdiction there
         over.

                  (iv) Prior to the appointment of the arbitrator, the Company
         or the Executive may seek provisional remedies, including, without
         limitation, temporary restraining orders and preliminary injunctions.
         After the appointment of the arbitrators, the arbitrators shall have
         sole authority to grant such provisional remedies as the arbitrators,
         in their sole discretion, deem necessary or appropriate.

                  (v) The arbitrators shall have the authority to award any
         relief permitted by relevant federal or state statute, including,
         without limitation, back wages, front wages, actual damages,
         compensatory damages, punitive damages, attorneys' fees, and costs
         associated with the arbitration proceeding. The arbitrators, in the
         award, may assess the fees and expenses of the arbitrators and of the
         arbitration proceeding and the witness and attorney's fees of the
         parties or any part thereof, against either the Company or the
         Executive or both of them, taking into account the circumstances of the
         case. Except as assessed by the arbitrators in the award, the Company
         and the Executive shall each bear their own costs in connection with
         the arbitration proceeding. Notwithstanding the foregoing, the Company
         shall bear 100% of the aggregate fees and expenses of the arbitrators.
